Patent CA-2219321-A1 (CA)
Inventor: ELIAS VICTOR
IPC: E01F15/04
Filed: 1996-04-26
Abstract: Système et procédé permettant d'élargir une autoroute (3) et de soutenir un mur anti-bruit (31), par une rangée unique de caissons (15) constituant la fondation (13) d'un mur d'appui (17) et d'un mur anti-bruit (31). Les caissons (15) comportent une armature d'acier orientée verticalement (46), dont une partie supérieure est intégrée dans l'armature d'acier (43) d'un mur d'appui (17) coulé sur place. Le mur anti-bruit (31) est monté sur les sommets des caissons, qui lui servent de support, et sert à limiter la transmission du son provenant de l'autoroute (3). Les éléments d'armature (46) orientés verticalement des caissons (15) sont situés à une certaine distance de la partie centrale de chaque caisson, en deux groupes opposés, de façon à garantir une résistance à la flexion maximale dans une direction orthogonale à l'autoroute, qui est la direction primaire selon laquelle la terre déplacée, le matériau de remblai compacté et le vent appliquent des moments de flexion au mur d'appui (17) et au mur anti-bruit (31). L'utilisation d'une seule rangée de caissons (15) présentant une résistance à la flexion élevée dans une direction orthogonale à l'autoroute réduit au minimum les matériaux et le travail nécessaires au soutien du mur d'appui (17) et du mur anti-bruit (31), et réduit de façon avantageuse l'espace nécessaire à l'excavation et à la construction des fondations (13).

Patent CA-2224065-A1 (CA)
Title: Cement treated with high-pressure co2
Inventor: JONES ROGER H JR
IPC: C04B41/50
Filed: 1996-06-03
Abstract: Cured cement matrices are exposed to high pressure dense-phase orsupercritical CO2 which enters the matrix through passages therein to neutralize the natural alkalinity of the cement so that alkali-intolerant materials can be incorporated in the cement. The CO2 converts calcium hydroxide in the cement to calcium carbonate and water, and the high pressure of the dense-phase or supercritical CO2 forms rounded, closely packed and aligned crystals with few or no visible pores or capillaries to enhance the homogeneity and strength of the cured cement and its bonding with, for example, uncoated reinforcing glass fibers. The supercritical CO2 can be used to transport other organic or inorganic materials, including pulverized metal, in solution or suspension into the interior of the cement matrix to alter its chemical and/or physicalcharacteristics.

Title: Automatic disposal of a waiting call during a call in progress
Inventor: DETERING GREIG R
IPC: H04M3/48
Filed: 1998-07-28
Abstract: In a computer system, a system for automatically disposing of waiting calls based on an entry in a caller information database. The invention includes a telephone interface that receives data from an ADSI network and is also connected to a regular telephone.      When call waiting caller ID information is received by the telephone interface, a database look-up is performed. Information in the database entry directs the system to automatically dispose of the waiting call through signals sent to the ADSI network.       Alternatively, a disposal option for the waiting call is to display on the computer screen a simulated ADSI phone display that allows the user to manually dispose of the waiting call.

Title: Opening system for beverage container
Inventor: LABUDA IVICA MARIA
IPC: B65D33/36
Filed: 1998-08-11
Abstract: An easy-open beverage container and opening system therefor includes first and second barrier walls having top edges and upper portions of opposite side edges which matingly face one another and which form an open top therebetween. A bifold membrane with a longitudinal fold is located in the open top. A membrane attachment securely attaches peripheral edges of the bifold membrane to adjacent top edges and upper portions of the opposite side edges such that the bifold membrane closes the open top and the facing top edges of the barrier walls are movable away from one another to expose the longitudinal fold for piercing by a straw. In a preferred embodiment, a side attachment securely attaches facing portions of the peripheral edges of the bifold membrane adjacent the upper portions of the opposite side edges so that the facing upper portions of the opposite side edges are not movable away from one another and thus the facing top edges tend to stay together and protect the bifold membrane. In another preferred embodiment, the opening system further includes a peel seal provided between facing portions of the peripheral edges of the bifold membrane adjacent the top edges of the barrier walls.      The peel seal provides a tamper-evident and sanitary seal for the bifold membrane which is easily broken. For easier opening of the peel seal, a respective pull tab or extension is present adjacent to respective peripheral edges of the bifold membrane adjacent the top edges of the barrier walls.

Title: Suppression of coherent rayleigh noise in bidirectional communication systems
Inventor: NUSS MARTIN C
IPC: H04B10/29
Filed: 1998-09-17
Abstract: Low-noise, bidirectional communications in a fiber optic cable is achieved by coupling a first end of the cable to a spectrally-sliced optical power source. A second end of the cable is coupled to an optical detector having a detector bandwidth, such that the bandwidth of the optical power source is greater than the detector bandwidth. When the bandwidth of the optical power source is large compared to the bandwidth of the detector, the beat frequencies resulting from coherent Rayleigh noise fall outside the bandwidth of the detector and are not detected.

Filed: 1997-03-14
Abstract: The present invention provides improved electrochromic layers, which comprise polymeric matrices with electrochromic solutions interspersed therein. Varying an electrical potential difference across a layer of the invention results in reversible variation in the transmittance of light across the layer because of electrochemical processes in the electrochromic solution of the layer. The invention further provides electrochromic devices, in which the electrochromic layers of the invention provide reversibly variable transmittance to light, and various apparatus in which the devices of the invention provide light-filtering or light-color modulation. Such apparatus include windows, including those for use inside and on the outside walls of buildings and in sunroofs for automobiles, and variable reflectance mirrors, especially rearview mirrors for automobiles.
